In an earlier series of blog posts, I outlined the process we follow when making a book at Cambridge. This process is a traditional book publishing workflow. It has people responsible for discrete tasks and linear process. The author produces the manuscript which the editor then edits and styles and passes onto the typesetter who lays the book out. The proofreader gives the book a once over, and then it is ready to print. If an e-book is needed, then a whole new process starts, with the PDF marked up for conversion to an epub. An external service provider typically completes this task. If we need to implement changes or reprint corrections to the title, then these changes must go back to the editor and then the typesetter. We must then implement these changes in the e-book version. This workflow is costly and time-consuming.
